Perhaps you should try some spelling variations:
wang liang » wang yang
yan liang » yang liang, you liang, yan wang
dang hari » dang hai
hua gain » heat gain, run gain, hua ban
kang han » kang chen, kong hang, zhang han
ying jin » yang jin, jing ji, yang jie
yan han » man han, yan zhang, yan clan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((yan han) OR (kang han)) hua gain ((((yan liang) or (wang liang))) or (ying jin)) dang hari ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan han) OR (kang han)) hua gain ((((yan liang) OR (wang liang))) OR (ying jin)) dang hari ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan han) OR (kang han)) hua gain ((((yan liang) or (wang liang))) or (ying jin)) dang hari ;".
• Adding a wildcard symbol may retrieve word variants: wan ((yan han) OR (kang han)) hua gain ((((yan liang) or (wang liang))) or (ying jin)) dang hari ;*.
